David Buchan/Getty Images(LOS ANGELES) -- The 2005 Porsche that Paul Walker was riding in was going "approximately 100-plus" miles per hour at the time of the accident that took Walker's life, according to police reports issued Friday.

The Los Angeles County Coroner's Office issued the final accident report from police regarding Walker's untimely death on Nov. 30. Roger Rodas, who was driving the car, also died in the crash.

"For unknown reasons, the driver lost control of his vehicle, and the vehicle partially spun around," the report says.

According to the report, the car, "struck a curb, and the driver's side of the vehicle struck a tree and then a light post. The force of the collisions caused the vehicle to spin 180 degrees."

Walker's side of the car also struck a tree before it burst into flames. This all happened at around 3:25 p.m. after Walker and Rodas had attended an event for the actor's charity, Reach Out WorldWide.

There were no signs that Rodas or Walker were under the influence of drugs or alcohol at the time of the accident.

When Walker died, it was reported that he had filmed about half of Fast & Furious 7, the franchise that made the actor a star. The Hollywood Reporter reported Friday that the plan is to retire Walker's movie character, Brian O'Connor, and not kill him off.

Walker was laid to rest on Dec. 14 at the Forest Lawn Memorial Park in the Hollywood Hills, Calif.
